Kia Rio: Evaporator Temperature Sensor Inspection

1.	Turn the ignition switch OFF.

2.	Disconnect the evaporator temperature sensor connector.

3.	Measure resistance between terminal “+” and “-” of evaporator temperature sensor.

4.	Connect the evaporator temperature sensor connector.

Run the engine and turn the A/C switch ON, then measure the voltage between the terminals of harness connector.
